The back of my throat looks distressed. No pain. It's reddish with areas of pale/granular looking patches in the upper left/right sides where the "big" taste buds rub into. The pale part is mostly transparent with pink tissue underneath. It's not a coating though it looks like it. The middle section is smooth and more normal looking. This area I use to help clear my throat and it gets a bit of "action" because of my sinus dripping due to alergies. There are small viens dispersed throughout that can be hardly noticeable to prominent when effort is applied during self examination by holding the tongue and holding breath. The "curtains" where the tonsils are "or should be as mine were removed" look similar but less aggravated and without the pale patches. Leading down into the throat it starts looking smooth and normal.

I had about a month of constant coughing and throat-clearing dealing with post nasal drip but now it's gone but the habit of cough/clearing happens once in a while but I fight it. Often my throat gets dry feeling especially at night if I breath through my mouth. It looks nothing like thrush.

Am I looking at just aggravation of the surface or a patch of Oropharyngeal Cancer? Would the cancer have to look like a tumor or can it be a "patch". It looks nothing like the cancers shown on the "net" that are either red and well defined, whitish patches, nodular tumors or sore like. I'll try to link to a pic tomorrow...

Do the obvious thing and get a doctor to shine a light down your throat. Even with pictures, it will be impossible to tell from here what it actually is. A lot of inflammatory of infectious type surfaces look exactly the same, and often need a swab to test for what is causing it. My bet, from your history is the "action" you mention has caused irritation and inflammation. But it still needs a professional look. Sera.
